Burglar Alarm PIRs & Detectors

Wireless detection devices for the ESP Fort Smart alarm range, each battery-powered and indoor-rated. The PIR motion sensors pick up movement across a room, with a pet-immune version that ignores smaller animals to cut false triggers. A vibration sensor flags attempts to force a surface, and door and window contacts report when an opening is breached. All link back to the Fort Smart hub.

Wireless detection for the home

Detectors are the part of an alarm that notices something is wrong and tells the hub to react. The units in this range are wireless and battery-powered, so they fix in place without cabling runs and report back over a radio link. That makes them straightforward to add room by room, and easy to reposition if the layout of a space changes. Without cabling to chase into walls, a setup goes in with little disruption, which suits a rented home as much as an owned one.

PIR motion sensors

Passive infrared sensors watch for the heat and movement of a person crossing a space, then signal the hub. A pet-immune version is built to overlook smaller animals, which helps cut the nuisance triggers that come from a cat or dog wandering through. Placing a sensor to cover an entry route or a hallway tends to give the most useful warning.

Contacts and vibration sensors

Door and window contacts work in two parts, with a magnet and a sensor that sit close together. When the opening is breached the two separate and the contact reports it, which makes them well suited to a front door, a back door or a ground-floor window. A vibration sensor takes a different angle, flagging the knocks and shaking that come with an attempt to force a surface before it gives way.

Building up cover

Because each device links back to the same hub, a setup can start small and grow as needed. A pair of contacts on the main doors, a PIR over a busy room and a vibration sensor on a vulnerable panel together cover the common ways in. The units are indoor-rated, so they are intended for use inside the home rather than out in the weather. Spacing them so their coverage overlaps a little leaves fewer blind spots for an intruder to slip through. Free UK delivery over £99, worldwide shipping.

Frequently Asked Questions

What is a PIR sensor?
A passive infrared sensor detects the heat and movement of a person crossing its field of view and signals the alarm hub. It is the usual choice for watching over a room or hallway.

What does pet-immune mean?
A pet-immune PIR is designed to overlook smaller animals so a cat or dog moving around the home is less likely to set it off, which cuts down on nuisance triggers while still catching a person.

How do door and window contacts work?
They come in two parts, a magnet and a sensor, fitted either side of an opening. When the door or window is opened the two parts separate and the contact reports the breach to the hub.

What is a vibration sensor for?
A vibration sensor picks up the knocks and shaking that come with an attempt to force a door, window or other surface, giving a warning of tampering before the surface gives way.

Can these detectors be used outdoors?
These units are indoor-rated, so they are meant for use inside the home. For exposed spots you would want a device built to handle weather instead.
